title: Observer strategy and radiographic classification of healing after grafting of cystic defects in maxilla: a radiological appraisal.
abstract: OBJECTIVE
  The aim is to radiographically quantify the bone density and relate the same with observer strategy in the bone healing.
  
  
  OBJECTIVE
  To assess pattern of bone regeneration following grafting of defects with hydroxyapatite after apicoectomy/cystic enucleation.
  
  
  METHODS
  An observer strategy involving trained and experienced examiners used in large series of cases, evaluated radiographically over a period of 1 year with intervals. The cases were grouped into different categories depending on (1) surgical site outline merging with material margin, (2) internal portion of surgical site (i.e. bone formation characteristics) and (3) density of surgical site. The radiographs examined by blind process and the findings were tabulated. Operating surgeon (oral surgeon) has done the interpretation of data to create observer strategy of grafting cases.
  
  
  RESULTS
  The outline of the defect was changed, partly reduced and completely absent along with remodeling, which showed ground glass, specular or trabecular pattern of bone over a time with increasing density correlating bone regeneration within a short duration. The applied strategy and classification are recommended for follow-up studies. In this study the characteristics of the new bone formation were also delineated. This strategy is helpful for follow-up studies; implant procedures and so; to know quality and condition of bone after treatment.
